Abstract
This paper presents a comparative study between lead-based and lead-free perovskite solar cells (PSCs)
utilizing Solar Cell Capacitance Simulator (SCAPS) software. Perovskite solar cells have garnered
significant attention due to their high efficiency and low-cost fabrication. However, concerns regarding the
toxicity of lead in traditional PSCs have prompted the exploration of lead-free alternatives. Through
simulation using SCAPS software, this study investigates the performance metrics, such as efficiency and
material properties, of lead and lead-free PSCs to provide insights into their potential as sustainable
alternatives for photovoltaic applications. Results show that methyl-ammonium lead iodide (MAPbI3) and
Formamidinium lead iodide (FAPbI3) perovskite solar cells exhibit efficiencies of 16.68% and 16.65%
respectively. The lead-free methyl-ammonium tin iodide (MASnI3) and methyl-ammonium germanium
iodide (MAGeI3) achieved efficiencies of 16.59% and 12.42% respectively. The findings suggest that while
lead-free perovskites offer promising alternatives, further optimization is necessary to match the efficiency
of their lead-based counterparts.
